Are Laptop Screen Extenders Backlit Or Edge-lit?

Types of Laptop Screen Extenders

Backlit Laptop Screen Extenders

Explanation of Backlit Laptop Screen Extenders

Backlit laptop screen extenders, as the name suggests, utilize a backlighting technology behind the screen to illuminate the display. This technology consists of a series of LED lights positioned at the back of the monitor, which evenly distribute light across the panel.

How Backlit Laptop Screen Extenders Work

When turned on, the LED lights emit bright and uniform light, illuminating the pixels on the screen. This backlighting technology allows for vibrant colors, sharp details, and excellent visibility, even in low-light environments.

Advantages of Backlit Laptop Screen Extenders

One of the main advantages of backlit laptop screen extenders is their exceptional brightness. The LED backlighting provides a high level of luminosity, ensuring that the display remains visible even in brightly lit or outdoor settings. This feature makes backlit extenders ideal for professionals who frequently work in different environments.

Additionally, backlit laptop screen extenders offer superior color accuracy. The uniform backlighting enables accurate reproduction of colors, allowing for precise image and video editing, graphic design, and other visually demanding tasks.

Disadvantages of Backlit Laptop Screen Extenders

One potential disadvantage of backlit laptop screen extenders is their power consumption. The LED backlighting requires a considerable amount of energy, resulting in a shorter battery life for both the extender and the laptop. This can be a significant drawback for users who rely on their laptops for extended periods without access to a power source.

Edge-lit Laptop Screen Extenders

Explanation of Edge-lit Laptop Screen Extenders

Edge-lit laptop screen extenders, on the other hand, utilize a different approach to lighting the display. Instead of having LEDs positioned behind the screen, these extenders have LEDs positioned around the edges of the monitor.

How Edge-lit Laptop Screen Extenders Work

When the edge-lit laptop screen extender is turned on, the LEDs around the edges emit light that is dispersed to the center of the screen through a light guide panel. This panel evenly distributes the light across the display, providing illumination to the pixels.

Advantages of Edge-lit Laptop Screen Extenders

One advantage of edge-lit laptop screen extenders is their slim and lightweight design. The absence of LEDs behind the display allows for a thinner and more portable device, making it easier to transport and integrate into your overall setup.

Edge-lit extenders also tend to have lower power consumption compared to backlit extenders. The LED lights situated around the edges require less energy to function, resulting in a longer battery life for both the extender and the laptop when in use.

Disadvantages of Edge-lit Laptop Screen Extenders

One potential limitation of edge-lit laptop screen extenders is their brightness. Due to the positioning of the LED lights at the edges, the illumination may not be as evenly distributed compared to backlit extenders. This can lead to slightly dimmer corners or edges, especially in darker environments.

Furthermore, edge-lit extenders may have limitations in color accuracy. While advancements have been made to improve color reproduction in edge-lit devices, some users may still notice subtle variations in color consistency across the screen. This can be a critical factor for professionals in graphic design, photography, or video editing.

Comparing Backlit and Edge-lit Laptop Screen Extenders

When deciding between backlit and edge-lit laptop screen extenders, it is essential to consider several factors that can impact your overall experience. Here, we will compare both types based on brightness, power consumption, color accuracy, uniformity, and cost.


Backlit laptop screen extenders generally offer higher brightness levels, making them suitable for outdoor use or well-lit environments. Edge-lit extenders, although less bright, are still adequate for standard indoor use.

Power Consumption

Edge-lit laptop screen extenders have an advantage in power consumption, as the LEDs around the edges require less energy compared to the backlit counterparts. This results in a longer battery life, which can be crucial for users who frequently work on the go.

Color Accuracy

Backlit laptop screen extenders excel in color accuracy, thanks to their uniform backlighting. The even distribution of light ensures precise color reproduction, making them ideal for professionals working with colors in their content creation workflows. Edge-lit extenders may have slight variations in color across the screen, which could impact color-sensitive tasks.


Backlit laptop screen extenders offer better uniformity in terms of brightness across the entire display. The LEDs positioned behind the screen evenly illuminate the pixels, providing consistent brightness levels. Edge-lit extenders may struggle with uniformity, with potentially dimmer areas at the corners or edges.


In terms of cost, edge-lit laptop screen extenders are generally more affordable compared to their backlit counterparts. If budget is a significant consideration, edge-lit extenders can provide a cost-effective solution without compromising essential features.

Choosing the Right Laptop Screen Extender

When choosing the right laptop screen extender, it’s essential to consider personal preferences and specific needs. Ask yourself questions like: What will the extender primarily be used for? Do you require high color accuracy? Will you be frequently working outdoors or in well-lit environments? Do you prioritize portability? By understanding your requirements, you can make an informed decision to ensure the extender perfectly aligns with your workflow and enhances your productivity.
